Why You Need a Portable DAC/Amp
Modern phones have eliminated headphone jacks, and the USB-C audio adapters bundled with phones are terrible. A dedicated portable DAC/amp dramatically improves sound quality for headphones and IEMs.
Measurement Methodology
All devices measured using Audio Precision APx555 analyzer:
- SINAD: Signal-to-Noise and Distortion ratio (higher = better)
- Output power: Into 33Ω, 300Ω, and 600Ω loads
- Frequency response: 20Hz-20kHz deviation
- Output impedance: Lower is better for IEMs
